if i click or enter an item contained in listview , it will display another form . on the form I want to display a row from my database like id , name, address and email in the textbox. and this code form call another form :

There are numerous solution for this problem. Usually the simplest one is to call the constructor of the second form passing the values you want to use there.
In your case the ID value of the ListView is just enough to build a query (in the second form) to retrieve all the users values
